Water contamination is a serious form of pollution, and one that can be challenging to rectify. There seem to be two main causes involved, and a variety of damaging effects on people and the biosphere, which we will discuss here.

Probably the main factor is the issue of emissions from cars, factories and other human activities. These emissions contain damaging pollutant particles which can contaminate rainwater run-off and thus enter the water cycle, by transferring through the water table into aquifers, streams and rivers. Filtration and processing are not really viable options for such large volumes of water, and so the water table remains tainted with these elements over long periods, as we see in Eastern Europe today. In situations where soil erosion and logging have already damaged the local environment, the accumulation can be very serious. The other major cause is accidental or deliberate dumping of waste products in places outside of controlled landfills or waste processing centres. Even small amounts of abandoned waste can enter water supplies through the ground, often undetected.

The effects on animal life can be severe, especially for species which are already endangered by such threats as poaching, habitat loss and food chain disruption. Contaminated water can lead to dwindling numbers or even potential extinction, as may indeed happen to the Asian tiger populations. The impact on human society can also be distressing, including the poisoning of drinking water, famine or drought due to lack of safe irrigation, and long-term loss of land as we see, for example, after the Bhopal poisoning catastrophe in India. Such effects tend to have an especially grave impact on the very poorest in society, with the least resources to counter the environmental effects.

Overall, we see that emissions and dumping are the main origins of the problem, and that the effects on both humans and animals are exacerbated by the existing environmental, criminal or social problems.

Although riding a bicycle is
clearly a better way to protect the environment than using other types of
vehicles, not many people around the world prefer this means of transport.
There are several causes of this unpopularity, and some solutions could be proposed
to promote the usage of bicycles.

To begin with, there are several
reasons why few people use bicycles to travel on a regular basis. Firstly, since modern life is getting much busier than in the past,
individuals nowadays want to spend as little time on transport as possible.
Therefore, they prefer to use other types of vehicles such as motorbikes or
cars which would take less time. Secondly, cycling is more physically demanding
than riding a motorbike or driving a car. This tends to discourage people from
choosing this method, especially on a hot and sunny day or when they have to
travel a long distance.

Several actions can be taken to
increase the popularity of bicycles. The first solution would be to make it more costly to own a motorbike or a car. This can be done by increasing
the price of petrol or raising tax on these vehicles. As a result, more people would choose
bicycles as their primary means of transport. Additionally, more lanes should be built to serve
only cyclists, which would make it much faster to travel with bicycles. The
final solution is to launch campaigns to raise citizens' awareness of the
harmful effects of motorbikes and cars on the environment, and this could
encourage people to cycle more often.

In conclusion, there are some
reasons why bicycles are becoming less common in today's world, and solutions
should be produced early to romote this environmentally friendly means of
transport.

The accelerating rate of natural
resources consumption has been a major topic of concern in recent years.
As some factors
are likely to
trigger this alarming
trend, a number
of drastic measures can be
employed to slow down the pace.

Perhaps it is the key role of
natural resources in boosting economic growth and the heavy reliance on natural
resources that accompany each other to create this dire situation. Today,
precious commodities from nature such as gas, oil and coal still remain crucial
to the operation of a country as transport and industries would grind to a halt
without the energy and fuel generated from these resources. In
emerging economies which
are striving to
rise, the demands
for resources are certainly on the increase. The dependence
on natural resources is also to blame as it is easier to exploit them from
nature than developing and converting to sustainable alternatives such as wind
and solar energy, which requires many years and great determination to
produce changes on a large scale.

In order
to alleviate the
existing problem, there
are some feasible
solutions. One step
to be mentioned is that the
authority should impose higher taxes on the use of natural resources to deter
further consumption. On the other hand, renewable energy sources such as solar
and wind power can be
developed to substitute
fossil fuels in
transport and manufacture.
Lastly, governmental
campaigns need to
be launched to
make individuals acknowledge
the risks of overusing natural resources through the
mass media.

In conclusion,
the overuse of the world’s
resources may result
in severe consequences, threatening the environment and
many people’s life, and strong measures must be implemented to tackle this
situation.

The overconsumption of natural
resources has evolved has a major topic of concern in recent years. This
alarming trend poses a number of serious threats to the world, and must be
addressed with a number of definite actions.

The increasingly high level of
natural resources exploitation can be hazardous in many ways. The most obvious
threat is that once the resources come to the verge of depletion, humans would
have to face the scarcity of fuels and materials. When oil becomes scarce and
more expensive, transport and heating would become less accessible and
affordable to most people. The shortage of resources also leads to stagnation
in other industries, for example, there would not be enough wood for furniture
production and not enough seafood for food processing. This would threaten the
business of thousands of companies, as well as the employment of millions of
workers in these fields.

Some measures can be taken to
mitigate the problem of over-consuming natural resources. The most practical
measure is to lower the demand for energy in every household. This can be done
by mass-producing energy-efficient household appliances and selling them at a
low price. Energy demand may also be cut by making saving energy the focus in
propaganda campaigns in various media channels. Another sustainable solution is
to promote environmentally-friendly technology. For instance, solar cells are now
sold in a small quantity and at a relative high price; they should be made
readier and cheaper for the public. Finally, the conservation and recovery of
natural resources, including seafood and forests, must be regulated by law.

To conclude, the overexploitation
of the world’s resources may result in severe consequences, threatening many
industries and people’s life. Strong measures, such as reducing energy use and
resource conservation and recovery laws, must be implemented to tackle this
situation.

The improvements in technology
currently bring about harmful effects on the environment. While some people
believe having simpler lives is the only solution, I would argue that
technological advances can help to tackle these environmental problems.

On the
one hand, it
is believed that
individuals need to
live simple lives
and rely less
on technology. The first suggestion is that people should walk or cycle
rather than drive cars. This is because the current number of cars being manufactured and used is increasing,
which causes high levels of exhaust fumes and makes air pollution become
serious. Additionally, people should try to reduce their consumption of
electricity so that the exploitation of natural resources such as fossil fuels
or nuclear power can be minimised. An example of this idea is the annual event
called Earth Hour where everyone is asked to turn their lights off for sixty
minutes.

On the
other hand, I
believe the developments
of technology can
greatly contribute to environmental protection. Firstly, because
of those improvements, people are able to come up with ways
to recycle materials
such as paper
or glass, which
reduces the problem
of waste disposal. Secondly,
technology can also help to create electricity using renewable resources. For
example, many countries in the world have built plants that utilise solar
energy to generate power. As a result,
it is not
necessary to rely
on non-renewable resources,
and people can
create electricity without significantly damaging the environment.

In conclusion, while some people
think that they should live simpler lives to prevent environmental issues, I
would argue that these problems can be dealt with by technological
improvements.

It
is true that humans can now set foot in wild regions far away from
civilisation. While I accept that this development can have certain benefits for the human race, I believe
that it is likely to
have a harmful impact on nature.

On
the one hand, undertaking expeditions to the wilderness can be valuable in
terms of both science and recreation. There are a considerable number of undiscovered secrets
that can be tremendously useful for researchers to conduct their studies. For instance,
environmental scientists can analyse the data about the thickness of ice layers over millions
of years in both hemispheres to predict the possible changes in global temperatures. Such
findings are crucial for the governments to develop appropriate plans to alleviate global warming.
Furthermore, the untouched beauty of these areas is usually appealing to travellers, providing
people with an attractive option of holiday destination or excursion.

However,
I would argue that these positive aspects are outweighed by the drawbacks. When people are given full and easy access to the distant and unpopulated areas,
there are likely to be more moving there to reside or start their business. It has been shown that
substantial damage has been done to nature such as massive deforestation or water contamination
due to humans’ lack of environmental awareness. If there is inadequate protection of the
environment from this type of action, wild regions in the world will no longer exist, unspeakably
affecting not only the overall ecology but also the lives of other people.

In
conclusion, it seems to me that the potential dangers of travelling to wild
environments are
more significant than the possible benefits for the mentioned reasons.
